Ubuntu Gnome Add/Remove programs

[chris1991]

I have now switched to Ubuntu (I posted earlier about compiling issues) and am now having trouble with the Add/Remove programs feature. Whenever I tick a program to install it gives me a message box saying "List of applications is not available. Please click reload."

Does your machine has internet access?

[chris1991]

Yes, I am browsing the forums now from the machine. Whenever I try to install something it says that "List of applications is not available. Please click reload.". So I click reload, enter the root password, it shows a progress bar saying it's dowbloading, all the message boxes dissapear looking like the problm is solved and then when I try to tick the intsall this app box, it wil go through the whole thing again.

Open Terminal and execute this

sudo apt-get clean all
sudo apt-get update

Try Add/Remove again. In case it doesn't work, post the contents of /etc/apt/sources.list file here. Either open that file in Gedit or execute this

cat /etc/apt/sources.list

Copy contents and paste here.
